GEORGE D. COLLINS, OF SPRINGFIELD, MASSACHUSETTS.

DOOR-FASTENER.

To all whom it may concern:

Be it known that I, GEORGE D. COLLINS, a citizen of the United States ofAmerica, residing at Springfield, in the county of Hampden and State oflvlassachusetts, have invented a new and useful Door-Fastener, of whichthe following is a specification.

My invention relates to improvements in; devices used for checking andsecuring doors at the bottom, and consists of a flat beak sharp at itsrear end, an oblique flat blade which is preferably provided withupwardly extending lugs or fingers, and a connecting wing between saidbeak and said blade, such wing extending laterally from the front partof the beak at the bottom and such blade extending downward and forwardfrom the front edge of said wing. The blade is designed to enter betweenthe bottom of-a door and either the floor or the saddle or thresholdbeneath said door, and the beak to engage the floor inside of the doorby sticking into the former, while the fingers afford means for properlyplacing or adjusting the fastener relative to the door and afford also abacking for the latter, under certain conditions which will be explainedhereinafter.

The object of my invention is to produce a device which is capable ofchecking a door being opened and of holding a door shut, a device inshort which is adapted to catch and fasten or secure a door in almostany position against force exerted on the door to swing it open, suchdevice being inexpensive to manufacture, simple in construction, andeflicient and reliable in operation.

The fastener may be employed, too, to hold a door open, as will be madeto appear in the course of this description.

I prefer to make my fastener of sheetmetal stamped out and struck up orbent into proper shape, although it might be made from some othermaterial in a different manner.

I attain the above-mentioned objects by the means illustrated in theaccompanying drawings, in which Figure 1 is a plan view of the blank outof which the fastener shown in the other views is formed; Fig. 2, a topview of the fastener as it stands in Fig. 4:; Fig. 3, a side elevationof said fastener showing its relation to a door, and, Fig. 4., anelevation of the opposite side of the fastener showing it in a differentrelation to a door, a threshold being present in this view but absentfrom the preceding View.

of sheet-metal, a blank is first cut out in the shape shown in Fig. 1,and this blank is then bent on'the dotted lines 6, 7, and 88 to pro-'duce a beak 9and a blade 10 with a connecting wing 11., and two fingers12, the dotted line 6 indicating the location of the bend between saidbeak and wing, the dotted line 7 indicating that of the bend betweensaid wing and blade, and the dotted lines 8 indicating the locations ofthe bends between said blade and said fingers. It will thus be seen thatthe wing 11 extends outward from one side of'the front partof the beak 9at'the bottom, with which said wing forms a rightangle, the bladelO'drops downward from the front edge of the wing at an obtuse angle tothe latter, and the fingers 12 project upward from the back edge of saidblade at the ends,

the angles between the blade and said fingers being obtuse also.

The beakQhas a generally curved appearance and its rear end is shaped toform a s ur 13 which is the part that engages the I oor.

The front edgeof the blade 10 is preferably beveled or sharpenedsomewhat, as shown at 14, to facilitate inserting the same beneath adoor when there is a mere crack between the bottom of the door and thefloor or threshold, and in any event to afford a blester engagement withthe floor or thresho In practice the blade 10 is introduced beneath thedoor as far as it will go and the spur 13 of the beak is thrust into thefloor which it penetrates a sufiicient distance to hold said dooragainstpressure from the side opposite to that where the fastener islocated. The more force applied to the door to move it against thefastener the deeper the spur is driven into the floor and the moresecurely the door is held. These results are produced by reason of thedownward and rearward pressure on the fastener due to the shape of thebeak and to the obliqueness of the blade. The door may only engage theblade as shown in Fig. 4, or it may engage both blade and fingers asshown in Fig. 3, according to the amount of space under said door, andit might engage the fingers alone where the amount of the aforesaidspace is usually large, but in any event the result is the same.Sometimes the door will ride up on the blade 10 until it encounters thefingers 12, when it will be prevented thereby from further movement inthat direction.

In each of the Figs. 3 and 4 the bottom part of a door is represented at15 and the floor at 16, and in the second of said views a saddle orthreshold appears at 17. Thearrows in these views indicate thedirections in which the doors 15 open. The back edge of the beak 9 mightbe depended on to check or engage the door when the blade 10 does not doso, in place of the fingers 12, were it not for the fact that in casethe fastener is not placed very carefully at right-angles to theadjacent side of the door or approXi- -mately so said door would verylikely knock said. fastener sidewise and thus render it noneffective,but said fingers prevent this since the engagement of either, one aloneby the door results in moving the fastener into proper position with theother finger against the door. Moreover the fingers furnish a better andmore substantial backing for the door than would the back edge of thebeak. The fastener is brought into proper relation to the door insubstantially the same way as that above explained in connection withthe fingers when said door makes first an oblique contact with theblade.

When employed to hold a door open the fastener is placed with its beakin engagement with the floor in front of the door and with its bladebeneath said door. Fig. 3 will serve as an illustration of this use, inaddition to that previously described. The shape of the fastener may bedeparted from in some minor details provided the general construction ismaintained, and as has been intimated the fingers may be omitted, butnot it is believed without impairing the efficiency of the device tosome extent.

I am aware that other devices adapted to engage both'the door and thefloor for the purpose of securing the former at the bottom have beenproduced, hence I do not seek to claim such a device broadly. a

What I do claim as my invention, and desire to secure by Letters Patent,is

1. As an improved article of manufacture, a door fastener comprising abeak for engagement with a floor, a blade for engagement with the bottomof a door and the threshold or floor under thesame, and a wingconnecting the forward part of said beak at one side with a portion ofthe rear edge of said blade.

2. As an improved article of manufacture, a door fastener comprising abeak for engagement with a floor, a blade provided with upstandingfingers at its rear edge, the blade being adapted to engage the bottomof a door and the threshold or floor under the same and the fingers toserve as abutments GEORGE COLLINS.
